I will say that at cPanel, we have a configuration where end users can
end up inside a mount namespace without /proc (depending on the
preferences of the administrator).  However, it's easy enough for us to
simply build without RUNTIME_PREFIX if necessary.

If we turn it on by default, it would be nice if we documented (maybe in
the Makefile) that it requires /proc on Linux for the benefit of other
people who might be in a similar situation.
